I'm running an Ubuntu 16.04 on my laptop, a normal process is to upgrade almost everyday, today when i enter "sudo apt list --upgradable" it showed me this message:

❯sudo apt list --upgradableListing... Donedebhelper/xenial,xenial 10.2.2ubuntu1~ubuntu16.04.1 all [upgradable from:9.20160115ubuntu3]N: There is 1 additional version. Please use the '-a' switch to see it

So i did as recommended, i enter:

❯sudo dh -adh: No compatibility level specified in debian/compatdh: This package will soon FTBFS; time to fix it!dh: Compatibility levels before 4 are no longer supported (level 1 requested)

Then i ran:

sudo apt upgradeReading package lists... DoneBuilding dependency tree Reading state information... DoneCalculating upgrade... Done0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

Why it isn't upgrading dh?, What can i do to fix it?

Thank you in advance.

  • I had the same issue, used synaptic and managed to get this upgraded. Source of the issue may have been having a ppa (tista/adapta) that included a debhelper version identical to the latest from xenial-backports, I used this command to figure out which: apt-cache policy debhelper– kpristJan 29 at 10:09

After looking for intricate solutions almost everywhere, i decided to try something simpler and transparent : use aptitude

sudo aptitude update

it found some broken packages, then:

sudo aptitude upgrade

it asked me if i wanted to repair the broken packages, i enter "y" and it started to fix all the broken packages.

I hope this solution can help you too.

    Sadly I cannot comment yet, I ran into the same problem. If you actually run:

    sudo apt upgrade debhelper

    it returns an error stating that

    Some packages could not be installed. This may mean that you haverequested an impossible situation or if you are using the unstabledistribution that some required packages have not yet been createdor been moved out of Incoming.The following information may help to resolve the situation:The following packages have unmet dependencies:debhelper : Depends: dh-autoreconf (>=12~) but 11 is to be installedDepends: dh-strip-nondeterminism (>=0.028~) but 0.015-1 is to be installedDepends: dpkg-dev (>=1.18.23ubuntu3) but 1.18.4ubuntu1.3 is to be installedE: Broken packages

    At least I I am running on KDE Neon LTS (based on 16.04) so I assume that error can only be fixed by the package managers.

    • This does not provide an answer to the question. Once you have sufficient reputation you will be able to comment on any post; instead, provide answers that don't require clarification from the asker. - From Review– Dave MJan 27 at 11:28
    • Wow thanks a lot, I even mentioned that. I hoped it might help someone with more experience. I hate those toxic communities where you cannot do anything without getting angry comments.– matt3oJan 27 at 11:35
    • Also the question itself is no question for this forum but rather for Ubuntu. It would help the person a lot more to point that out but hey, let's rather refer to the guidelines which won't help anyone– matt3oJan 27 at 11:37
    • @matt3o I'm going to try to show you that this isn't about being "toxic" but rather it's about being on-point, focused, topical. SO sites are about getting down to business: find your answer and get out. The downvote is because your "answer" here isn't helpful for the poster's question. You're simply stating "I have this problem too," which doesn't help anyone get a solution. When someone new comes here to find an answer and reads your response, they're not helped at all. To mitigate this problem, SO sites rank responses. This way someone can easily filter out this not-useful response.– MalcolmFeb 14 at 21:22
    • Yes I know that. But 1) other communities just convert those "wrong questions" into comments. As you surely see I cannot comment yet 2) how about a short "thanks for trying to help but that's not the way". I will delete this question anyways. Just saying this is a negative environment. Be a little nice and people will love to help out.– matt3oFeb 14 at 21:25
